Nickel Smelting at Shimura Plant

Histone Methylation in Nickel-Smelting Industrial Workers

BACKGROUND Nickel is an essential trace metal naturally found in the environment. It is also common in occupational settings, where it associates with various levels of both occupational and nonoccupational exposure In vitro studies have shown that nickel exposure can lead to intracellular accumulation of Ni2+, which has been associated with global decreases in DNA methylation, increases in chr...

Heavy metal pollution induced by a ferro-nickel smelting plant in Greece.

Seven heavy metals, Co, Cr, Cu, Fe, Mn, Ni and Zn, were measured in marine sediments, plants and invertebrates in the vicinity of a ferro-nickel smelting plant in Greece. The concentrations of metals in the sediment were higher than those found in the average unpolluted Greek coastal sediment. High levels of metals were observed in the gastropod molluscs, particularly Cerithium vulgatum, which ...

Assessment of the impact of heavy metal pollution from a ferro-nickel smelting plant using biomarkers.

A set of biomarkers was used to assess the impact of heavy metal pollution by a ferro-nickel smelting plant in Larymna bay (North Evoikos Gulf, Greece). These included a biomarker reflecting health status of an organism (scope for growth, SFG), a cellular biomarker of heavy metal exposure (composition of metal-containing granules), and two biochemical biomarkers reflecting oxidative stress (glu...

Shimura curves of genus at most two

We enumerate all Shimura curves XD 0 (N) of genus at most two: there are exactly 858 such curves, up to equivalence. The elliptic modular curve X0(N) is the quotient of the completed upper halfplane H∗ by the congruence subgroup Γ0(N) of matrices in SL2(Z) that are upper triangular modulo N ∈ Z>0. The curve X0(N) forms a coarse moduli space for (generalized) elliptic curves equipped with a cycl...
